Synopsys Design Compiler | Tutorial 2021

Once the design is loaded, you must ensure all module references are correctly resolved and that the code contains no structural syntax anomalies.

dc_shell> source run_synthesis.tcl

Design Compiler operates in two primary execution modes depending on your automation and visualization requirements. Command Line Mode (Recommended for Automation) Execute synthesis non-interactively using a Tcl script:

Registering the outputs of major design blocks makes predicting input/output delays much easier, which helps Design Compiler optimize boundary logic more effectively. synopsys design compiler tutorial 2021

Schematic symbols used for visual reporting tools. Sample .synopsys_dc.setup File

The data arrived too late. You must re-optimize or change your code architecture. 7. Exporting Output Files

: Includes all libraries needed to resolve references in the design. It must contain the target_library as well as any architectural macro cells, RAMs, IPs, or pad cell libraries. The asterisk ( * ) represents the tool's internal memory. Once the design is loaded, you must ensure

The path is too slow. You must optimize your RTL code, increase the clock period, or use compile_ultra to fix this issue. Area Report Analysis

Before starting, ensure you have the RTL code, standard cell libraries, and a Synopsys Design Constraints (SDC) file.

write_sdc ./results/top.sdc

During the link step, Design Compiler resolves references between your modules and connects them to the libraries listed in your link_library variable. The check_design command identifies potential synthesis hazards such as latches, multi-driven nets, or unconnected ports. 4. Defining Design Constraints (SDC)

Builds the design hierarchy and identifies generic logic. elaborate top_module Use code with caution. 3. Applying Design Constraints
